ELEKS vs Thoughtworks: overview
ELEKS
ELEKS began in Lviv in 1991, which makes it one of the oldest software companies in Ukraine. It now lists Tallinn, Estonia as its corporate headquarters and keeps a London office on Beech Street. Around 2,000 specialists work on custom software, data science, and research and development projects, mostly from Ukraine and Poland. Its long history with Western European clients shows in fairly mature delivery processes.
Thoughtworks
Thoughtworks was founded in Chicago in 1993 and has had a significant UK presence for decades. Apax Partners took it private in a deal valued at about $1.75bn that closed in late 2024, after a NASDAQ listing in 2021, and the transaction came with job cuts affecting about 6–7% of its 10,500 staff. It is known for its Technology Radar and for shaping agile and continuous-delivery practice. It has delivery centres in India, China, Brazil and elsewhere, but UK engagements usually lean on senior onshore consultants.
